Currently the automatic NOINDEXing of new articles on English Wikipedia expires after 30 days. The original agreement was to have it expire after 90 days (under the incorrect assumption that English Wikipedia was using the default 90 day value of $wgRCMaxAge). Let's switch PageTriage to use it's own config variable for this expiration (rather than $wgRCMaxAge) and set it to 90 days by default.
